Is my air conditioner lacking fluorine? Do I need to have workers come to my home to check it regularly?
The worker said whether there is a lack of fluoride or not, I can completely judge for myself.
Air conditioners lacking fluorine are bound to be accompanied by two situations:
① The cooling effect becomes worse, but it should be ruled out that it is caused by weather reasons (overheating, excessive humidity, etc.). The cooling effect caused by lack of fluorine is often more extreme, that is, the temperature in the room does not drop no matter how long the air conditioner is turned on.
If you still feel unsure, you can find a thermometer to measure the temperature of the air outlet. If the air outlet temperature (preferably measured when it is just turned on) is higher than 20℃, it means that the cooling effect is too poor.
If conditions permit, you can also measure the air outlet temperature of the indoor and outdoor units at the same time. Or measure it when it is just turned on. If the temperature difference between the two is less than 8℃, it means that the cooling effect is not good.
② Frost, lack of fluorine will definitely cause frost! The indoor unit is easier to observe. We can open the panel and remove the filter to observe the evaporator below half an hour after turning on the air conditioner to see if there is any frost.
Frost on the evaporator means lack of fluorine. In severe cases, a layer of frost will even form on the filter, which means that the lack of fluorine is more serious. Frost on the filter will also cause water leakage in the indoor unit, so water leakage in the indoor unit may also be due to lack of fluorine.
There are two valves on the side of the outdoor unit. When the air conditioner lacks fluorine, frost will also form on the valves. Moreover, the outdoor unit frosts earlier than the indoor unit, so if you can see the outdoor unit, it is best to judge by this method.
Precautions for adding fluorine:
① Refrigerant will not leak for no reason. We need to consider whether the machine has been moved or repaired recently. If so, it may be caused by the refrigerant leakage during the moving and repair process. Just add fluorine.
② If there is a sudden lack of fluorine during normal use, it may be caused by pipeline damage. At this time, not only fluorine should be added, but also the pipeline needs to be repaired or replaced (there is usually a lot of oil at the leak point).
